To address this issue, we propose a signal denoising method based on ensemble empirical mode decomposition (EEMD) and MSPCA.  ...  Synthetic tests demonstrate that the EEMD-MSPCA-based method can provide good signal denoising results and is superior to the low-pass filter, wavelet reconstruction, EEMD reconstruction, Hankel–SVD, EEMD-Hankel–SVD  ...  authors gratefully acknowledge the financial support of the China Postdoctoral Science Foundation (2020T130757), Basic Scientific Research Operating Expenses of Central Universities (2020CDJQY-A047), and  ...
